Knowing Jesus isn’t just about following rules. You have to KNOW Jesus. He is a person. He is a personal God.
We can know a lot of stuff about Jesus and never know Jesus personally.
Beg Jesus to show himself to you this Advent. Invest, spend time, and make sacrifices for Jesus. We must make time every day to spend at least a few moments in quiet prayer with Jesus. Read the Word of God. Receive the sacraments frequently.
